Awesome Deal!
No need of a huge review here. Very sturdy, carpeting is great, leaves me with alot of space in my trunk. It holds 2 kicker CVR's that are 1600 watts max. Wont be dissapointed if you buy this! I've had it for 6 months and not a single problem!

Solid As A Rock
Box was bought for the Pioneer 3000 watt 12" Subs and its a Perfect Match for them plus,it saves trunk space. Subs Mounting Holes are nice cut. However,I did add a extra lining of polyfil but,it was nothing to it. "GOOD BOX" For Subs that requires small enclosures!

Impressed
I have had many complements from friends seeing this box in action and it even hits harder than some ported boxes. My friends own with the same subs I guess the filling inside really makes the difference but the only down side is that the box is rather small in person but that gives u more trunk space. Overall the box does its job just fine.

Nice box, no screws
Box is fantastic. Comes with padding, perfectly sized. My dual 12 inchers sound fantastic.
Words of warning: Does not come with screws or internal wiring. That's up to you.

Very Lavish Subwoofer Housing
Excellent quality for the price. Perfect compact rectangular prism that produces distinct clear slams. Strong and sturdy, exactly what your looking for.

Great box!
I received this box with a bass combo deal, and I wasn't expecting the best quality. But when I received it I was pleasantly surprised. It is made of 3/4 inch MDF which makes it solid and heavy and very sturdy. Its sealed nicely and I have had no air leaks whatsoever, my only complaint is the use of cheap binding posts. Prefab boxes can work just fine, you just have to pay close attention to the air requirements of your sub and that of the box.

Great Box for a Great Price.
Put my 2 Rockford P2D2 12's in here along with my Hifonics 1000 RMS amp. These things slam in my Regal. Recommendation to people with older cars and higher wattage systems, dynomat your trunk, and better yet the rest of your car. You will enjoy the quality of your sound so much more. If you have the money I say it's well worth it. Also make sure your license plates are secure on your car, no one likes trunk rattle. Overall I give this Sub Box 4.9 stars. The only thing I would suggest is maybe a second layer of polyfil, it's pretty thin with just one layer. Wasn't a big deal, I went and picked up a bag of polyfil for around $5 and lined it myself.
